1 Timothy 4:1
The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons.
The issue of people abandoning their faith is not up for debate. Paul writes to Timothy as a warning that this would happen and he states that it is a definite. What theologians debate – and won’t be answered here – is whether this abandoning of the faith is a loss of salvation.
There are two sides to this debate. One group says that if a person had faith they were saved and then they abandoned that faith, they lost their salvation. The other side says that if they abandoned their faith, they were never really saved to begin with because if they were truly saved, they wouldn’t have abandoned the faith.
Both sides reach the same conclusion however; those who abandon their faith are in trouble. We don’t know why some people come to church for years and suddenly disappear. Many times there is sin involved, either by the person who leaves or by other people in the church who hurt them.
Other times people have their faith tested and they believe that God failed them rather than it is they who have walked away from God. In the end, it doesn’t matter why people abandon the faith, it doesn’t lead to a good result.
When your faith is tested and you are tempted to walk away from God, remember this verse. Satan is a master deceiver. He will tell you lies about God and everyone around you. But they are only lies. God will never abandon you even in the worst of times and we must continue to hold fast in our faith.
